You can work around the delays by having multiple spamd processes per cpu or by reducing the timeouts. The latter may result in less accuracy, so I wouldn't that unless you have a high enough load to justify it. Most DNS look-ups run in parallel with the regex rules. In 4.0/trunk that also applies to Pyzor, Razor, and DCC. If you have an Authentication-Results or Received-SPF header above your first/lowest trusted header SA can use that instead of doing lookups.
